Yes, those are the retracts I used (even for the nosegear).
The main gear wheels are foam Du-Bro 150MW 1-1/2 Mini Lite wheels, and I robbed the 1-1/4" foam nosewheel from a Hobbico Skyfly 2 (replacement part number HCAA3880).
I flew it several times today; the wheels and retracts worked great, and the plane will fly easily at only 50% throttle and a little "up" trim. It's got plenty of power and speed (just under 60mph on the radar gun). It's a real hoot!
